Retirement of individual apps?

Hi I'm just wondering something about the email I received this morning. I use the Newsstand iOS Walking Dead app on my iPad to read the compilation volumes and own the first 6. I want to keep all my Walk Dead books in the same app but from what I read today I will no longer be able to buy any in this app and only buy them in the iBooks store. I just want to check to see if that is correct?
Along with that question I prefer the way the books flow in the Newsstand app but if I will no longer be able to buy any new ones in there, is there anyway to migrate my purchases to iBooks so that I can have all the issues in the same app/format and not have to have two apps to read the books. I'm a little OCD when it comes to stuff like that and would really prefer not to shell out $60 again for the books I own.

Hi Jordan. Good news! Newsstand apps are NOT going away... just our iPhone and iPad "Graphicly Comics" apps that let you browse and buy from our whole store. In fact, we plan on releasing more great Newsstand titles here soon.

So, just to be clear, there is no need to switch to iBooks for reading the Walking Dead if you prefer the Newsstand experience. We'll keep distributing new Walking Dead books to both channels, so folks can purchase and read wherever they prefer.

(FYI: We'll soon be releasing an update to the Newsstand app that lets you sync your Newsstand purchases with your Graphicly.com account, allowing you to read these books on the Web and Facebook, too, without having to buy again.)

Glad to hear the Walking Dead newstand app is not going away! I have really enjoyed reading the my first 14 of the trade/collections, and I'm still trying to catch up! Purchasing through the app has been effortless, and I have had a flawless experience so far... Thanks, again, for keeping it up and running!
